Let's explain how RPMs for RHEL are built: We use a subscribed RHEL 8.x machine and mock build these on it. Mock initializes its own buildroot based on the latest RHEL 8 CDN content, see[1]. This means that the minor version of the buildroot is independent of the minor version of the host. However, we currently upload RPMs to a directory whose name consists also of the minor version of the host. Our hosts are currently running RHEL 8.3 so the RPMs are uploaded into rhel-8.3 directory despite them being built in the RHEL 8.4 buildroot (RHEL 8 CDN buildroot specifically). This means that we cannot guarantee that they are installable on RHEL 8.3 which is weird. This commit adds a special case for hosts that run on subscribed RHEL and thus build RPMs in a buildroot constructed from RHEL CDN. These RPMs are now uploaded into rhel-8-cdn directory. This change more accurately reflects the way we build our RPMs and removes some confusion.
